probability = 2/7
to be exact, 28/97 (about 28.87%)
A Leap year has 366 days. in which you have 52 weeks and 2 days. the 2 days may be sun,Mon mon,Tue tue,wed wed,THu, thu,Fri FRi,SAT sat,sun so you have 7 options among which 2 u can choose.. so the answer is 2/7 for having 53 Sundays. The probability of having 53 Thursdays is also 2/7. The probability of having either 53 Sundays or 53 Thursdays is 4/7.
None of them. The probability of an event cannot be greater than one. Besides, every leap year will have 366 days, not 53!

There is only one girl out of 12 students so the probability that the girl is selected is 1/12.
The probability is 10 percent.

It depends on what the random variable is, what its domain is, what its probability distribution function is. The probability that a randomly selected random variable has a value between 40 and 60 is probably quite close to zero.
random sample
When each member of the population has the same probability of being selected as a member of the sample.
The probability is approx 0.81
It is a simple random sample.
This is called a random sample.
